Napolean tells the other animals that the project will require harder work and reduced rations for all of the animals, except, of course, the pigs. Life for the animals begins to get worse. They work harder and longer, 60 hours a week, including Sundays. Orwell writes in the beginning of chapter VI:
"All that year the animals worked like slaves. But they were happy in their work; they grudged no effort or sacrifice, well aware that everything that they did was for the benefit of themselves and those of their kind who would come after them, and not for a pack of idle, thieving human beings."
Because of the push to complete the windmill, the farm is neglected. Shortages necessitate trade with humans which causes another violation of the “unalterable” commandments of Animal Farm.
